CULTIvA'rOR. I

Application filed June 8;

. ing to provide a Construction in Which the Vator that the beams'Which-carry the soil- I indicated at v6 beamsi'or the soil engaging members may be made short and thus not only economize in' the amount of material composing the beams, but also enhance thest-rength and stiffness ofthesame. f v

A further object is to so construct a cultivator thatthe forward portions of the mem bers of two-part beams-shall be made to embrace the carryingavheels-and connect with the framework I at points Within the radii-of the wheels.

i v I A further objectis to so construct a cultiengaging members shall be, connected with the framework approximately'in horizontal alinement with the axes of the Wheels.

further object is to provide, in a three row cultivator, means whereby .thc centraI beam and the soil-engaging member carried thereby may be adjusted laterally to adapt the cultivator to roxvs which may not be spaced equi-distant apart. i V J With these and other objects in View, the invention consists in certain novel features of construction and combinations of? parts as hereinafter set forthand pointed out in theclaims.

Inverted U-sha'ped supports or yokes '9 depend ttrom end portions of the'rear transverse frame bar 1 and have their upper horizontal members 10 rigidly bolted to said frame bar 1,- said yolres being braced by U-shaped braces 11 having their parallel arms secured to the parallel arms offlthe yolr es 9 and their connecting members '12 securely bolted ,to the front transverse frame ba'rQ, Brackets 13 are secured ,to one ole and provide bearings for the v er'tical portions 1% of axles which. pass through the hubs of carrying heels '15,-said Wheels bearm of each supporting"yoke?9 .ing thus so locatedthat they Will be partially en'ibraced by the supporting yokes 9." Near they lower ends of the depending arms oteach supporting {yoke 9 shoulderv bolts 16 are located, and-to'these bolts" the forward ends of the members 17, 17 of a split or two partgcultivatorbeam 18 are connected, so that each of said beams 18 is connected vvith the framevvorlr in horizontal alin'ement with theaxis of acarrying Wheel and straddles the latter. The members 17 ofeach cultivator beam18 are"con nected rearwardly of the carrying ,vvheel by a transverse brace 19, and in rear ot'fs a-id brace, the beam members are made to converge and merge nto parallel-rear: portions wh ch are bent downwardly to form a stand ard QO With which a cultivator soil-ngag-- ing' member 21 is connected.

(after having. loosened the. nuts so as to adapt the cultivator to rows which may not be spaced equi-distant apart.

Brackets 33 are secured to the rear verse frame bar 1. near respective ends there: of and provide bearings for the rounded end portions on shaft 34. This shaft is prefen ably made angular in cross section, and setooth ed segments 34 corresponding in number with the culti: vator beams. An auxiliary lever is pivotally connected with each carriesQa suitable manually operable detent for'cooperation with theteeth of the erg ment. "Each lever 35 is provided "with a crank arm 37 with which one end of a rod 38 is connected, the other end of said rod being connected with one of the cultivator'beams. The lower rear ends ofthe rodsfor the cultie are connected with the centhe members 17, 17 of said beams and the rod 38 for the central beam is connected with the latter over-its longitudinal axis. It will be observed that the lever rods 38 are connected with the longitudinal central'portions of the cultivator beams practically;:.di- ,rectl y behind the wheels. The pressurejrods 38.1therefore, exert central pressure on the soil-engaging elements carried by .said beams. This construction 'is particularly valuable when split or two-part beams are employed, as the proper and even penetra- .tion of the ground by the soil-engaging elementswill be insured. i

A main lever 39 is secured to the shaft 34 and is provided with a suitable manually opthe teeth of a segment-.40 secured to the rear frame bar 1. It is apparent that when the auxiliary levers 35 are locked to their segments and themain lever 39 is operated, all-of the cultitaneously. .A spring 41 may be employed to beam lifting operation, one endof said spring being secured to a bracket 42 se cured to the front frame'beam 2 and the transsegment 34 and rocking movement about yolzes,

other end being secured to an arm 43 secured to the shaft 34. p I v A support'44 for a'seat 45 is attached to the frame of the lcultivator "and projects rearwardly therefrom, the seat 45 being located over the soil-engaging member 21 car:

ried .byithe central beam 22.

The axles 14 are provided at their upper ends with forwardly projecting arms 46,

and a lever 47 having a forwardly projecting arm 48 and laterally projecting arms 49, is pivotally supported by a bracket 50 secured to the rearframe bar 1. The "axle arms 46' and the arm connectedby a rod or bar 51 pivotally attached thereto. 1 nected with the arms 49 ofthe lever 47 for operating said lever axles to shift the wheels for guiding purposes Having fully described my invention what I claim as'new and desire to secure by Letters-Patent, is: r r y 1.
